hallo Remi,
from what you say it seems that the back of the 110 is more "rounded/egg shape" than the 107 (which I suppose should have a straighter rail line).It's due,off course,because the max width of the 110 is wider.
If it's true can we say that the 110 suits better the downwind courses?
Got a quick line from a Starboard PRO who just give the 110 a spin.Only words he said were that the 110 is surely better than the 107 for the 8,6 and that it's a totally different board than the 107.Pharaphs no more explication...
